The simple economic reason bitcoin will fail as replacing fiat. It is not centrally controlled. The power to adjust the supply of money is extremely crucial in order to maintain liquidity in money markets. This didn't happen overnight it evolved to this stage through painful lessons of history. Without this aspect bitcoin is inefficient as money.
You challenge one of the main features of Bitcoin. History shows that governments cannot resist printing money for themselves, or causing inflation to reduce the impact of government debt. The US Federal Reserve props up the banking system by creating money to loan at low rates to banks, and creates money to purchase toxic assets from them. Central control of Bitcoin, I believe, will be limited to prudent government regulations necessary to protect consumers, while encouraging innovation.
Because business cycles are currently related to credit expansion and contraction, a Bitcoin dominated economy may not need central banks to create money to prop up collapsed equity markets. A bitcoin economy is one in which credit as we know it will be replaced by something else. Loans cannot be easily made when denominated in a deflationary currency because the loan interest rate must be greater than the rate of deflation, which is currently about 10x annually. I think that future homeowners will rent-to-own rather than obtain 30 year Bitcoin mortgages. The monthly payments would be indexed to the rate of deflation.
As a technology I think cryptocurrency has potential. The public ledger aspect of it is extremely intriguing. Bitcoins potential is in money transfer not as currency. This is what GS and Buffett said and I agree. I predict that in the future the banks will create some digital cash using public ledger idea. But its not a separate currency but based on dollars in your bank account. Thats what consumers want. Something like M Pesa or Ripple
According the economic principal popularized in Crossing the Chasm, it will be difficult for entrenched financial institutions to create new financial products that cannibalize their existing revenue streams. The US Federal Reserve has been pushing for immediate settlement of transactions but that is simply not good enough. Bitcoin's no-recourse feature makes settlement immediate. Bank card operators charge high fees to pay for the fraud that the current system allows and which Bitcoin prevents.
I suggest you look into a coursera.org course called "economics of banking" taught by prof Merhling of Columbia U. Theres no politics in this course. Just banking, how it functions, its history. I think you will understand money much more and how banking infrastructures weakness is not because Central Banking or fractional reserve banking. It has more to do w regulations surrounding derivatives, prop trading, shadow banking, etc. Things that can't be solved by inventing a new currency

If you want to design something useful, then design it to work on top of what we have not replace it. Why do you want millions of indiviual networked bankers? Can they provide financial services like loans or credit? Deal liquidity? Make markets? Or are they there just to support the network for blockchain? Why do you need a new curency when it has to be converted back to dollars? I just don't get what problems bitcoin is supposed to solve
I am familiar with the stack model of software development, e.g. building RDF on XML, building HTTP over TCP/IP, etc. But Bitcoin startups are discarding the upper layers of the financial services stack and plugging in at the lowest possible level for a re-engineering of the system. For example, consider a Bitcoin ATM compared to a bank ATM. The Bitcoin ATM uses the internet to operate same as a bank ATM - but the Bitcoin ATM does not involve the vast overhead of the banking infrastructure. A bitcoin point of sale device likewise plugs into the cashier station in a manner similar to a bank card POS device. A Bitcoin wallet on a smartphone fits in a pocket in a manner similar to a conventional leather wallet holding bank cards.
Billions of individual Bitcoin users will be their own bankers but will not themselves be providing banking services to others. Bitcoin is programmable money that permits new financial services to be operated by third parties that add value to the system.
If indeed Bitcoin becomes the dominant financial instrument, then converting back to fiat would not be needed. For example, it is difficult for taxing authorities and public utilities to accept bank card payments from taxpayers and ratepayers because of the high merchant fees that cannot reasonably be passed on to the public. But Bitcoin is free for the receiver so when taxing authorities accept Bitcoin then the last reason to convert to fiat is gone.
Bitcoin is supposed to solve all the problems caused by the legacy financial infrastructure - the most severe of which I believe is the horrific misallocation of scarce resources given inflation, and the boom and bust business cycles caused by fiat-created credit.
